Prince William honoured his beloved grandmother in a moving tribute telling how the Queen steered him through his saddest days.
The Prince of Wales, 40, told of his gratitude for the vital guidance the late monarch gave to him, to wife Kate, the Princess of Wales, and to their three children, which will show them the way as their royal roles develop.
The Queen stayed with William and brother Prince Harry at Balmoral in the days after their mother Princess Diana died in 1997, when William was just 15.
